In stating these matters, I speak an open and disinterested language, dictated by no passion but that of humanity. To me, who have not only refused offers, because I thought them improper, but have declined rewards I might with reputation have accepted, it is no wonder that meanness and imposition appear disgustful. Independence is my happiness, and I view things as they are, without regard to place or person; my country is the world, and my religion is to do good.

The mind that becomes soiled in youth can never again be washed clean. I know this by my own experience, & to this day I cherish an unappeased bitterness against the unfaithful guardians of my young life, who not only permitted but compelled me to read an unexpurgated Bible through before I was 15 years old. None can do that and ever draw a clean sweet breath again on this side of the grave.

The Bible itself can be used for both good and evil. That doesn't mean it's flawed. It means that it is perfect.

When a man is getting better he understands more and more clearly the evil that is still left in him. When a man is getting worse, he understands his own badness less and less.

For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Eph. 6:12 (NIV)

The bible divides mankind, god will decide our fate.
